Air quality today

The air quality in Mortsel today is classified as Moderate. The primary pollutant identified is PM2.5, with a measured concentration of 12.43 µg/m³ based on five valid observations reported through OpenAQ.

These measurements reflect the current state of fine particulate matter in the city without additional context or interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Mortsel air‑quality dataset contains six measured variables – PM1, PM10, PM2.5, relative humidity, temperature and the particle counter UM003 – all supplied by a single Airgradient‑AW sensor. In total there is one reporting row, so the coverage reflects conditions at that specific location rather than a citywide network.

The most recent readings are from 2026‑02‑10 19:00 UTC for PM1 (7.59 µg/m³), PM2.5 (12.43 µg/m³), relative humidity (71.33 %), temperature (10.93 °C) and UM003 (1 312 particles/cm³). The PM10 value is older, last updated on 2025‑01‑13 23:00 UTC at 60.50 µg/m³, indicating that this particular metric has not been refreshed for over a year. All other pollutants show a single recorded value, so the median, minimum and maximum are identical.

Because only one sensor contributes data, the range for each pollutant is effectively zero – the reported figure is both the lowest and highest observed. This limits insight into variability across Mortsel; conditions can differ in other neighbourhoods or at different times of day. The freshness of most parameters (within three days) suggests that recent atmospheric conditions are being captured, but the outdated PM10 measurement highlights an inconsistency in data recency across pollutants.

Overall, the dataset offers a snapshot rather than a comprehensive picture: it provides current values for five variables and an older value for PM10, all from a single point source. Users should keep in mind that air quality can change spatially within Mortsel, and the limited station count means the figures may not represent the whole municipality at any given moment.

Data notes

The data shown for Mortsel reflects five valid measurements and was updated within three days, with the latest refresh recorded at 2026‑02‑10T19:00:00+00:00. This snapshot provides a brief view of current air quality conditions; however, pollutant levels can differ across neighbourhoods and change throughout the day, so local variations may not be captured in this summary.
